I had a pair of trousers made for me by a tailor in Gaziantep, but only because he was the father of one of my students. I got them for free, or I would have never had them made.
Why do you want to wear tailored clothes there? Do you think G-tep is the fashion mecca of southern Turkey?

As for why she'd want clothes tailored, I know I've never had clothes as nice as the ones I got made in Hong Kong. I afterwards learned I'd paid about three times the going rate, and if I'd haggled I'd have gotten them for less than at upscale shops in the US.
